Abstract

The invention relates to a trail traffic buckle accessory alloy pretreatment and graphene material compound corrosion resistance technology which comprises the following steps: S1, performing alloy pretreatment on the surface of a to-be-corrosion resistant object to form a compound layer on the surface thereof; and S2, then coating the surface of the compound layer of the to-be-corrosion resistant object with a graphene corrosion-resistant material to form a compound coating. The compound corrosion resistance technology comprises the S1 of obtaining the compound layer (an alloy co-diffusing layer). The alloy co-diffusing layer can be combined with a metal matrix firmly, so that the electrochemical corrosion problem can be solved. Meanwhile, the problem of collision in a construction process is solved without affecting the hardness of metal. The alloy co-diffusing layer can be combined with the graphene corrosion-resistant coating well, so that the comprehensive corrosion-resistant ability of a product is improved. By combining the two, corrosion-resistance and collision resistance of the product can be solved at the same time.

Description

technical field

[0001] The invention belongs to the technical field of metal surface anticorrosion treatment, and in particular relates to a compound anticorrosion process of alloy pretreatment and graphene material for rail transit buckle fittings. Background technique

[0002] With the rapid development of our society, high-speed railway has entered a new period of rapid development. The construction of high-speed railway is not only an increase in speed, but also an all-round improvement in technology. During use, the railway track system is often accompanied by mechanical vibration, impact, wear, and corrosion of steel caused by harsh weather conditions in the field. How well the anti-corrosion problem is solved and the choice of anti-corrosion measures directly affect the safety of train operation.

[0003] Alloy pretreatment or anti-corrosion coatings traditionally used on railways are currently facing new challenges. Coating technologies such as zinc-rich coatings an...
